Annotation Type SafeVarargs

A programmer assertion that the body of the annotated method or
constructor does not perform potentially unsafe operations on its
varargs parameter. Applying this annotation to a method or
constructor suppresses unchecked warnings about a
non-reifiable variable arity (vararg) type and suppresses
unchecked warnings about parameterized array creation at call
sites.

In addition to the usage restrictions imposed by its @Target meta-annotation, compilers are required to implement
additional usage restrictions on this annotation type; it is a
compile-time error if a method or constructor declaration is
annotated with a @SafeVarargs annotation, and either:

the declaration is a fixed arity method or constructor

the declaration is a variable arity method that is neither
static nor final.

Compilers are encouraged to issue warnings when this annotation
type is applied to a method or constructor declaration where:

The variable arity parameter has a reifiable element type,
which includes primitive types, Object, and String.
(The unchecked warnings this annotation type suppresses already do
not occur for a reifiable element type.)

The body of the method or constructor declaration performs
potentially unsafe operations, such as an assignment to an element
of the variable arity parameter's array that generates an unchecked
warning. Some unsafe operations do not trigger an unchecked
warning. For example, the aliasing in
